## Intended Use

Hevylite Human IgG Kappa is a quantitative in vitro assay performed on the Siemens BN II nephelometer for the measurement of IgG kappa (IgG heavy chain and lambda light chain intact immunoglobulin) in serum. Measurement of Hevylite Human IgG Kappa is used alongside Hevylite Human IgG Lambda to calculate the IgG kappa/IgG lambda ratio. The Hevylite Human IgG kappa/IgG lambda ratio can be used when monitoring previously diagnosed IgG multiple myeloma and is used in conjunction with other laboratory tests and clinical evaluations. The assignment of complete response is reliant upon other tests including immunofixation, bone marrow and urine assessments. Hevylite Human IgG Lambda is a quantitative in vitro assay performed on the Siemens BN II nephelometer for the measurement of IgG lambda (IgG heavy chain and lambda light chain intact immunoglobulin) in serum. Measurement of Hevylite Human IgG Lambda is used alongside Hevylite Human IgG Kappa to calculate the IgG kappa/IgG lambda ratio. The Hevylite Human IgG kappa/IgG lambda ratio can be used when monitoring previously diagnosed IgG multiple myeloma and is used in conjunction with other laboratory tests and clinical evaluations. The assignment of complete response is reliant upon other tests including immunofixation, bone marrow and urine assessments.

## Device Story

Quantitative in vitro nephelometric assay; measures IgG kappa and IgG lambda concentrations in human serum; utilizes sheep anti-human IgG antibodies specific to junctional epitopes (heavy/light chain contact). Performed on Siemens BN II nephelometer; instrument automatically dilutes calibrator to generate calibration curve; light scatter intensity proportional to antigen concentration. Used by laboratory technicians in clinical settings to calculate IgG kappa/IgG lambda ratio; ratio changes used to monitor treatment response in IgG multiple myeloma patients. Results interpreted alongside SPEP, immunofixation, and bone marrow assessments to determine clinical status (e.g., complete response, progressive disease). Benefits include objective monitoring of monoclonal protein levels to assist clinical decision-making regarding patient response to therapy.

## Clinical Evidence

Retrospective study of 127 IgG multiple myeloma patients (428 sequential samples). Compared Hevylite IgG kappa/lambda ratio response classifications against NCCN v1.2011 criteria. Sensitivity 93% (95% CI: 89-95%), specificity 75% (95% CI: 65-83%). Weighted kappa analysis showed 0.75-0.78 agreement with clinical reference methods. Study confirmed utility in monitoring treatment response.

## Technological Characteristics

Quantitative nephelometric assay. Reagents: polyclonal monospecific sheep anti-IgG antisera (combined heavy/light chain), calibrator, controls. Preservative: 0.099% sodium azide. Platform: Siemens BN II nephelometer. Connectivity: instrument-based processing. Storage: 2-8°C.

## Regulatory Identification

An immunoglobulins A, G, M, D, and E immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the immunoglobulins A, G, M, D, an E (serum antibodies) in serum. Measurement of these immunoglobulins aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents.

Dear Mr. Kenny:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
